Yes. I figured that out. But I've discovered that at the [reboot] step
I managed to misbootd into the squeeze kernel with the wheezy udev, so
your analysis is dead on.
I had even installed the wheezy kernel (version 3.0.something), but even
so, I find myself unable to boot it, as described in another post in this

I don't know. It sounds like an idea. How does one do this?

I'm starting to think that the simplest solution might be to wipe the
wheezy partitions clean, copy in the squeeze partitions again, and do the
whole thing again, this time *not* rebooting when NFS doesn't work but
instead running apt-get -f install.
But it's still not clear how to solve the boot problems. It seems that
something -- the 'core'? the initrd? the intermediate bootloader stages?
are too big for the embedding area, also something about a cross-disk
boot. The boot drive of this system is *not* the drive the system
partitions are on. Evidently a cross-disk boot of squeeze works, bot one
for wheezy with the new kernel doesn't. I've tried grub on both systems
without success. I've tried lilo on the squeeze system. The only thing
still to try is running
on wheezy (still booted with the wrong kernel, of course, until I
actually get a bootloader to boot the right kernel).
